Shift-Share method is a kind of international universal analysis method accounts for the reasons of regional economic development variety.This paper conducted a deep research on the connection between the regional industrial structure and economic development variety via using Shift-Share analysis in city county level

and explained the reasons of regional economic depression in Xinjiang.By the means of evaluating regional industrial structure and competitive capability

the whole sudy area was divided into four diffdent economic growth types: First one include the regions which have both industry structural advantage and competitive advantage

5 diffdent cities and counties belong to this type

and account for 5.88% of whole study area;Second one include the regions which have industry structural advantage and competitive disadvantage

21 diffdent cities and counties were included in this type

and have the proportion of 24.71%;Third one include the regions which have industry structural disadvantage and competitive advantage

14 diffdent cities and counties belong to this type

and account for 16.47% of whole study area;Last one include the regions which have both industry structural disadvantage and competitive disadvantage

45 diffdent cities and counties were included in this type

and have the proportion of 52.94% .We can see from the results that

firstly

the average economic growth rate of most regions in Xinjiang commonly under that of Xinjiang;Secondly

distribution of cities and counties with similar economic growth characteristics showed the tendency of spatial centralization;Thirdly

poor competitive capability and regional back ground are the main reasons caused the slow economic growth of approximately 80% of cities and counties inXinjiang;Finally

Some cities and counties with relatively high economic development level have remarkable advantage in their industrial structure

so it can be achieved that under the poor competitive capability and regional back ground

the proper organization and adjustment of regional industrial structure have a great significance on promoting economic rapid growth in Xinjiang.
